Paper Giant Magneto-impedance And Magnetic Properties Of Co-rich Crossed Amorphous Microwires: Focus On Angular Dependence

Giant magneto-impedance (GMI) effect is defined as a large change in the impedance of a soft magnetic conductor which an alternating current (AC) flows through in the presence of an applied magnetic field [1]. A soft magnetic amorphous microwire of diameter ~ 100 μm consisting nominal composition Co68.15Fe4.35Si12.5B15 was prepared by in-water quenching technique [2]. A length of ~ 3 cm of the microwire was taken for the study. Two amorphous wires with the same size were symmetrically installed a measuring sample holder with an angle of θ between them (θ=15, 30, 45, 60, 75 and 90o). The value of the room temperature magnetization of the crossed wire was obtained from the measurements with a vibrating sample magnetometer (VSM, Lake Shore 7404) of shorter samples of about 5 mm long
